One of these days Chip Kelly will realize the only real chance you have to put pressure on a high-scoring team is to try to convert on fourth down with your offense in their territory while the game still is close.

He’ll understand more of that ridiculously long list of NFL rules, including the one where you can call time to keep your quarterback from sitting out a play after the officials think he’s hurt and stop the game.

That rule could work really well when you’re inside the 10-yard line of the opposition in a close game.

Then there’s the up-tempo offense which so far has generated a ton of yards but in the past two games has struggled to score points. The Eagles haven’t dominated at all like they did in the first half of the first game Kelly unveiled his version of the spread.

Everyone figured Kelly’s rah-rah, up-tempo approach to the NFL after a stellar tour at Oregon would have bumps in the road. But now it’s going to get much more difficult as the Eagles jump into the division portion of their schedule. They take on NFC East opposition three times in the next four weeks, including the Giants twice, starting today.

The division teams now know a lot more about Kelly and his offense than the Redskins, in the first week of the season. What one of them said this week is very interesting.

“When Chip came into the league people tried to study and become more aware of it,” Giants head coach Tom Coughlin said. “They went back and looked at a lot of different things. So the pace, and the way in which the theory behind the pace, and the performance of the athletes is outstanding. But it’s a relatively novel scheme for the NFL and it’s obviously very, very good. A lot of people are talking in very positive terms about Chip and his theories.”

A relatively novel scheme for the NFL? Remember, that’s coming from a guy who wanted to hire Kelly as a quality control, not a position coach. A guy who has a Super Bowl championship ring for both hands.

Despite a three-game losing streak, Kelly and the Eagles seem loose. He kidded the players about telephoning the NFL commissioner’s office to see when he could pick up the trophy should the weekend fall their way. The Eagles will be in first place by a tiebreaker should they beat the Giants and the Cowboys lose to the Broncos Sunday.

Kelly interrupted a news conference this past week to address an especially loud LeSean McCoy jogging by the tent on the way to practice.

Said Kelly, “LeSean! LeSean! We good? We good? Can we continue? All right buddy! Love ya!”

Kelly is loose. But is that a good thing?

“It’s very important,” quarterback Michael Vick said. “You can’t come out and display any kind of discomfort to the team. His attitude is to stay positive and to keep working.”

Stay positive, keep working and if we may interject, keep learning. The Chip Kelly experience still is a relatively novel deal for the NFL.

Brandon Boykin expects to get plenty of work against Victor Cruz today when the Eagles oppose the Giants.

If Boykin picks off Eli Manning, he’s not going to celebrate by trashing Cruz’s salsa dance.

“No, first of all I don’t even know how to salsa,” said Boykin, tied for the team lead with, uh, one interception. “I’m going to leave that to him. Dexter McCluster, I like what he did last week. He salsa’d and he kicked the ground. No, I’m going to keep it cool.”

McCluster (http://youtu.be/deKRZuPBQdw) parodied Cruz’s dance after an 89-yard score with a punt return sparked the Chiefs to a rout of the Giants last week.

Cruz has scored four of the Giants seven touchdowns.

NOTES: After getting tough with the media, Vick toned down his dislike for questions he felt implied he wasn’t getting rid of the ball quickly enough. “But if you all think I’m holding the ball too long,” Vick said after challenging the media to review game film frame by frame to prove he wasn’t, “then maybe you all are right.” Maybe he realized he did hold the ball too long a few of those times … Eagles linebacker Connor Barwin has a brother, Sean, who resides in New York. Sean Barwin will be the only Eagles fan in the group attending the game today at MetLife Stadium. “This summer I met plenty of Giants fans and they’ve explained the rivalry to me very clearly,” said Barwin who rated their input M for Mature. “They pretty much said they’d cheer for me except for the Giants game.” … Eagles safety Patrick Chung is questionable for the Giants game with a mysterious shoulder injury. Limited in practices, Chung has made his presence felt helping teammates, including rookie cornerback Jordan Poyer. “He’s kind of taken me under his wing, helped me learn the defense a lot,” Poyer said. “I always go over to his house and his wife is cooking me dinner all the time. I think Pat and me just had a natural connection when I first got here. We’ll play video games, watch film and tell jokes.” … Wide receiver Riley Cooper (6-3, 222) thinks the Eagles’ struggles scoring touchdowns in the red zone are about making “good decisions. That’s all we’ve got to do. The players are there. The play-calling is there. But the players have got to execute, that’s all. It will come. This is all new to everybody. It takes time. It’s four games in. Everyone has got to get on the same page.” … Finally, after un-following @John Elway Bet I just had to take a look at some of the guys he follows on Twitter. The list includes @CharlieSheen and @RealJerryJones. Interesting.
